Abstract

After the COVID-19 pandemic, the need for precise disease diagnosis and monitoring increased in importance.Many researchers and scientists have used a variety of nanomaterial’s, including metal nanoparticles (NPs), metal oxide NPs, quantum dots (QDs), and carbon nanomaterial’s, such as graphene and carbon nanotubes, to create highly effective and sensitive biosensors (CNTs). Among them, CNTs have been regarded as significant candidates for biosensing channels because of their outstanding physical characteristics, including high electrical conductivity, robust mechanical properties, plasmonic characteristics, and others. The review introduces CNT-based biosensing systems and reports on various sensing techniques including electrochemical, optical, and electrical methods. Furthermore,these biosensing platforms demonstrated excellent sensitivity and high selectivity against viruses as well as virus DNA morphology. In light of this incredible potential, healthcare and public health can be greatly enhanced by CNT-based biosensing technologies.
